I will appreciate if you can suggest some particular product that has good results.

Wow. I just don’t know about using silicone. In my experience not much sticks to it. I’ve always heard NOT to use it on an RV and I guess I’d try using the polyurethane stuff or lap sealant. I believe lap sealant is specifically made for RVs so maybe give that a try. Lots of people use the term “silicone” rather generically for any caulk (like calling any tissue a “Kleenex”) but you’d not think a Thor guy would make that mistake. I expect you’ll be fine whatever you use if you keep an eye on it going forward. Which you should be doing anyway. Good luck!
